Well seeing that I have some of the ES 82's I'll comment on them.
Long and the short of it... they are marvellous eyepieces(for the price). Really good contrast. The 14mm is a particularly nice example as well. I'll use M47 for example. The Planetary nebula in the centre of that star cluster stands out very well at a even a moderately LP effected dark site. Using an OIII filter didn't really improve the image, it mainly just dimmed the star cluster around it. Still needed in the city though.
The build quality is excellent. I mean their completely airtight and water proof. Who else can boast that?
They have nice and soft roll up rubber eyecups. Eye relief is comfortable across the 6.7mm, 14mm and 30mm.
The 30 mm is especially comfortable. I've kept my face at that eyepiece for nearly an hour last night trying to spot galaxies in LP sydney skies. I didn't feel tired or strained at all. You can kind of just rest your face on it. Just frustrated at not having much luck ha-ha. The moon seriously didn't help.
Also, I have no problem at all seeing the entire field of view at once. You just gotta put your eye center, then start looking around. They arn't picky on eye placement either. Theres no kidney beaning or blackouts, at least that I've experienced. If you want you can look back a bit further from the eyepiece and move your head to look around as well to see the edge of the field of view. They have nice big lenses as well.
The 82 degrees of AFOV is very nice, especially since my dob doesn't have any tracking and I don't have to nudge the scope often.
They are well corrected. I've tested them down to f4.5 in 13.1 Inch Dob and I think mental4astro's 17.5 inch f4.5. In those scopes, the stars are pin point to about 85%. Which isn't bad considering I only plaid $99 AU each for the 6.7mm and the 14mm. At f4.9 which is what my scope is, the correction is good to about 90-95% for the 6.7mm and 14mm. I'll admit the correcti0on of the 30mm at f4.9 is probably best to about 80%. But, then I've looked through a 31T5 and at about F4.9 they are well correct to about 90%. But, they do cost twice as much.
Not going to say for a second they are as good as a Televue offering. But, generally speaking they are 1/3 the price.
With the money I saved I was able to buy a coma corrector. It helps pick up that 20% of field that needs the extra correction.
Not bad planetary eyepieces either. I've never seen an objectionable views. 82's are wonderful on the moon. Feels like your an apollo astronaut
flying around the moon. I love it.
The 30 mm does have a blue ring of fire on the extreme edge on really really bright objects. Like the moon. But, honestly I find the moon boring at only 50x. So I don't care.
All that being said. I am extremely satisfied with these eyepieces. Price/performance ratio is off the chart!. I'd recommend them to anyone not willing to spend the $$$ on the Televue offering.
